Sequences are common in puzzles. Most of them are boring, but here are a few which are more fun (and possibly cheating...)

There is the start of a sequence of numbers below. Every time you click on 'Next' you will get the next. Can you work out what the sequence is?

1

- You will need to have several numbers before the hint will help.

Solution - but don't click here until you've tried it for yourself. The solution is more fun, and makes more sense, after your own attempts.

Here is a sequence. What is the next number?

**8**

**8,000,000,000**

**8,000,000,008**

**8,000,000,800**

Solution - but don't click here until you've tried it for yourself. The solution is more fun, and makes more sense, after your own attempts.

This one just needs a little thought (and so doesn't have a hint). Which is the first number, spelt as a word, has its letters in alphabetical order? ONE doesn't because N comes before O and E comes before both of them. By number, we mean, of course, the positive integers.

- but don't click here until you've tried it for yourself.

This one is definitely cheating!

Here is a sequence. What is the next letter? (And why?)

**E G E G E V W G**
